Sir, I had ordered track suit of XL size and have been send M size, which is too short and is of no use to me. The XL size confirmation was taken by me by atleast 3 to 4 times but still M size track suit has been despatched. I need immediate change of size.
Even my name which was confirmed many a times i.e. Harish Hira but on mailing invoice it is mentioned as Mr.Hri Shira.

I wonder how people work in an international organization like Reebok, the name has been mis spelled and wrong delivery of track suit size is made, even those so many times confirmation was sought by me for the size of track suit.
